Quantitatively, the molar fraction of the carbamate was obtained by integration of the relevant peak areas in the 1H NMR spectra while the molar fractions of free MEA and MEAH+ were determined according to the MEAH+ dissociation constant and pH value of the solution. Furthermore, as the CO2...

Although some formate species may also be observed on H-IO and Si-IO, their peak intensities are weaker compared to E-IO. These collective results indicate that amine-functionalized In2O3 exhibits strong CO2 adsorption, bonding, and activation abilities due to the presence of grafted NH2 groups...
Primer specificity was checked by the occurrence of a single peak of expected size during dissociation experiments. Analysis of the 18S ribosomal RNA was performed using the Ribosomal RNA Control TaqMan assay kit (Applied Biosystems) to normalize gene expression. Results were expressed as arbitrary ...
We then confirmed that HarA formed no by-product; during the HarA-catalyzed harmaline-degrading reaction, only the peak derived from 2-AIMA was observed in the LC chromatogram and MS spectrum of the corresponding compound (Supplementary Fig. 12). Fig. 2 Identification of the reaction formula of...

The 1H-NMR spectroscopy demonstrated that 1-hexadecylamine functions as blocking agent in this polymerization. The DSC thermograms showed that the extra peak (peak (II)) and the melting peak (peak (I)) of AM-6/66/1010 are moving left and the glass transition temperature of AM-6/66/1010 ...
Also evident in the NMR was a loss of intensity of the CF3 resonance peak relative to that of pure Viton®). This loss of spectral signal is attributed to crosslinking near the CF3 sites, leading to the following structure as well as other structures from double bond rearrangements (see...
1.A composition comprising a colloid which is stable under physiological pH and ionic strength, said colloid comprising particles having a core and a shell:a) wherein said shell comprises a polymer having amine functionalities;b) wherein the particles have a volume-weighted mean particle size diam...
